If you have unusual requirements (for example, if you want to change all
annotations of a certain type), you may be able to edit annotations more
efficiently using a text editor such as emacs. Since annotation files
are not text files, however, you will need to convert your files from binary
to text form to edit them, and then convert the edited text back to binary
form in order to use them further with WAVE . You can do this using rdann and wrann (see
rdann(1)
and
wrann(1),
in the WFDB Applications Guide, for details).
